The adjusting bracket 300 may include a first connecting portion 310 and a second connecting portion 320, the second connecting portion 320 may be connected to the first connecting portion 310, the first connecting portion 310 may be connected to the adjusting leg 200, the second connecting portion 320 may be rotatably connected to the universal wheel assembly 100, and rotation of the second connecting portion 320 relative to the universal wheel assembly 100 drives the adjusting leg 200 to rotate around the universal wheel assembly 100. In this way, the adjusting leg 200 can flexibly rotate around the universal wheel assembly 100 along with the second connecting portion 320, which is beneficial for adjusting the adjusting leg 200 to a stable supporting position, so as to stably support the refrigeration equipment on the ground, and further improve the stability of the refrigeration equipment. It is understood that the first connection portion 310 may be one end of the adjusting bracket 300 in the above-described embodiment, and the second connection portion 320 may be the other end of the adjusting bracket 300 in the above-described embodiment.

The first connecting portion 310 and the second connecting portion 320 are integrally formed, thereby facilitating the improvement of the strength of the adjustment bracket 300, and further facilitating the adjustment bracket 300 to more reliably connect the caster assembly 100 and the adjustment foot 200.

The second connection part 320 may be rotatably connected to the fixing base 120 around the vertical direction of the mounting surface 121a, for example, the second connection part 320 may be provided with a bracket connection screw 321, and the external screw 122b of the fixing base 120 may be connected with the bracket connection screw 321 of the second connection part 320, so that the fixing base 120 and the second connection part 320 may be connected by screw. In this way, the second connecting portion 320 and the fixing base 120 are connected through threads, so that the adjusting bracket 300 can drive the adjusting leg 200 to rotate, and the adjusting leg 200 can be adjusted to a proper position. In addition, the adjusting bracket 300 and the fixing seat 120 are adjusted through threads, so that the operation is simpler and the cost is lower. In addition, since the bracket connecting screw 321 of the second connecting portion 320 is connected with the external screw 122b of the fixing base 120, the universal wheel assembly 100 can play a role in supporting the refrigeration device in the process that the second connecting portion 320 drives the adjusting foot 200 to rotate, and the second connecting portion 320 is sleeved on the periphery of the fixing base 120, so that the second connecting portion 320 can drive the adjusting foot 200 to rotate relatively easily, thereby being beneficial to the operator to flexibly drive the adjusting foot 200 to rotate through the second connecting portion 320 with less effort.

The bracket connecting screw 321 may be a trapezoidal screw structure, that is, the cross section of the bracket connecting screw 321 is approximately trapezoidal, so that the bracket connecting screw 321 and the external screw 122b have a larger contact area, thereby being beneficial to improving the strength and rigidity of the connection between the adjusting bracket 300 and the fixing seat 120.

Referring to fig. 10, when adjusting the adjusting bracket 300, an operator often holds the first connecting portion 310 with his or her hand to rotate around the universal wheel assembly 100 relative to the universal wheel assembly 100. Since the edge of the adjusting bracket 300 is sharp, the edge of the adjusting bracket 300 is easily cut by the hands of the operator during the operation. In view of this, in some embodiments, the adjusting bracket 300 may include a hemming structure 340, and the hemming structure 340 may be located at edges of the first and

second connection portions

310 and 320, wherein the hemming structure 340 may be formed by winding the first and

second connection portions

310 and 320 inward, so as to wrap the sharp edges of the adjusting bracket 300, and thus, when an operator rotates the first connection portion 310 around the universal wheel assembly 100, the operator's hand is not easily cut, which is beneficial to protecting.

Further, when adjusting the adjusting bracket 300, an operator often holds the first connecting portion 310 with his or her hand to rotate around the universal wheel assembly 100. Since the end angle of the adjusting bracket 300 is sharp, the end angle of the adjusting bracket 300 is liable to hurt the hands of the operator during the adjusting process. In view of this, in some embodiments, the end surface of the first connecting portion 310 facing away from the second connecting portion 320 may be provided in an arc surface, so that the end angle of the first connecting portion 310 is prevented from being relatively sharp, and thus an operator can safely perform an operation.

When the refrigeration unit is open, the center of gravity of the refrigeration unit tends to shift forward, resulting in easy tipping of the refrigeration unit. In view of this, in some embodiments, the caster assembly 100 may be spaced apart from the adjustment foot 200 such that the caster assembly 100 is spaced apart from the adjustment foot 200 by a distance. In this manner, the adjustment foot 200 may be rotated relative to one another about the caster assembly 100 such that the adjustment foot 200 may find a better support point, for example, the adjustment foot 200 may be rotated to a position near the door of the refrigeration appliance, and the caster assembly 10 may also be adaptively adjusted in the event that the center of gravity of the caster assembly 100 changes, thereby better supporting the refrigeration appliance and avoiding tipping of the refrigeration appliance.

In some embodiments, the first connection portion 310 may be provided with a plurality of mounting portions 330, the plurality of mounting portions 330 may be spaced apart along the length direction of the adjustment bracket 300, and the adjustment foot 200 may be selectively connected to one of the mounting portions 330. In this way, the distance between the adjusting leg 200 and the universal wheel assembly 100 can be adjusted through the plurality of mounting portions 330, so that the adjusting leg 200 can be connected by selecting a proper mounting portion 330 according to the size of the refrigeration equipment, and the universal wheel device 10 is improved in universality, so that the universal wheel device 10 can be widely used.

Further, the mounting portion 330 may be disposed in a hole shape, and threads are disposed in the mounting portion 330, so that the adjusting foot 200 may be in threaded connection with the mounting portion 330, so that the adjusting foot 200 may be quickly connected with the adjusting bracket 300, and the operation is simple and the manufacturing cost is low.
